Convert Bytes per second to Kilobits per second
Convert Bytes per second (B/s) to Kilobits per second (kbit/s) instantly and accurately.
Conversion Formula
kbit/s = B/s × 0.008
About Bytes per second
Byte per second (B/s) = 8 bit/s. The natural unit for file transfer speeds, disk I/O, and memory bandwidth reported by OS tools and storage benchmarks. ISP 'Mbit/s' ÷ 8 = MB/s download speed: a 100 Mbit/s connection delivers ≈ 12.5 MB/s. USB 2.0 = 60 MB/s; SATA III = 600 MB/s; Thunderbolt 4 = 5,000 MB/s. 1 B/s = 8 bit/s.
About Kilobits per second
Kilobit per second (kbit/s) = 1,000 bit/s (SI). The classic unit for narrowband telecoms: dial-up (V.90) = 56 kbit/s; ISDN BRI = 64-128 kbit/s; G.711 VoIP = 64 kbit/s; Opus (WhatsApp, Discord) = 6-510 kbit/s adaptive; Bluetooth Classic = 1,000 kbit/s; Zigbee/Z-Wave = 20-250 kbit/s. 1 kbit/s = 1,000 bit/s = 125 B/s.
